Abstract
The utility model provides a boiler safety valve, including relief valve casing, case, poppet spring, adjusting nut and activity stop valve, movable stop valve be connected with the blow vent, fixing device swing joint on activity stop valve and the relief valve casing, and contacting with the case on the top of activity stop valve, be equipped with the poppet spring device on the case, the re -entrant portion of relief valve casing installation case is equipped with adjusting nut, two positions about divideing into the relief valve casing through adjusting nut. Whole device is effectual has realized the dismantlement, and can solve boiler safety valve's fine setting atmospheric pressure function, and easy operation can further popularize and apply.
Description
Technical field
The utility model relates to relief valve device field, is specifically related to a kind of boiler safety valve.
Background technique
Boiler safety valve belongs to self-acting valve class, and be mainly used on boiler, pipeline, pilot pressure is no more than setting value, can run important protective action to personal safety and equipment.For air and steam safety valve, many employing Unseal type safety valves.Selecting for safety valve product, should determine by actual sealing load, general boiler safety valve also all adopts Unseal type safety valve.
But the safety valve usually adopted in boiler for producing process is now often in order to strengthen overall structure, all adopt and fixedly mount at boiler, and elastic force is larger, if there is the exhaust failure of boiler, make dismounting difficulty, again change and higher expense can be produced, while simultaneously present most of boiler safety valve adopts manual tune, the air pressure function of finely tuning boiler safety valve can not be realized.
Model utility content
For the deficiencies in the prior art, the utility model provides a kind of boiler safety valve, can effectively achieve for convenience detach of device, and can solve the fine setting air pressure function of boiler safety valve.
For realizing above object, the utility model is achieved by the following technical programs:
A kind of boiler safety valve, comprise safety valve housing, spool, valve core spring, adjusting nut and movable stop valve, described movable stop valve is connected with ventilating hole, movable stop valve is flexibly connected with the fixing device on safety valve housing, and contact with spool on the top of movable stop valve, described spool is provided with valve core spring device, and the re-entrant portion that described safety valve housing installs spool is provided with adjusting nut, by adjusting nut, safety valve housing is divided into upper and lower two positions.
Preferably, described movable stop valve and ventilating hole contact position are provided with cushion seal pad.
Preferably, described spool top is provided with a draw ring.
Preferably, described movable stop valve, spool all adopt titanium alloy to make.
Preferably, the top of described movable stop valve is connected by plug tenon mode with spool.
The utility model provides a kind of boiler safety valve, by adjusting nut, safety valve housing is divided into upper and lower two positions, and spool, valve core spring that in the safety valve housing hollow of adjusting nut, position is installed, adjusting nut can be regulated to control the compression degree of valve core spring, thus control activity stop valve is pressed in the pressure size of ventilating hole, to reach the effect of effective vernier control boiler pressure, and safety valve housing can be dismantled by adjusting nut, conveniently keeps in repair.Movable stop valve, the spool of whole device are connected by plug tenon mode, effectively achieve processing, easy to maintenance, also save the cost making workpiece simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 overall structure schematic diagram of the present utility model;
Wherein: 1, safety valve housing; 2, spool; 3, valve core spring; 4, adjusting nut; 5, movable stop valve; 6, ventilating hole; 7, draw ring.
Embodiment
For making the object of the utility model embodiment, technological scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the present embodiment provides a kind of boiler safety valve, comprise safety valve housing 1, spool 2, valve core spring 3, adjusting nut 4 and movable stop valve 5, movable stop valve 5 is connected with ventilating hole 6, movable stop valve 5 is flexibly connected with the fixing device on safety valve housing 1, effectively can realize dismounting, reduce the fault that mechanical device occurs, and contact with spool 2 on the top of movable stop valve 5, spool 2 is provided with valve core spring 3 device, the re-entrant portion that safety valve housing 1 installs spool 2 is provided with adjusting nut 4, by adjusting nut 4, safety valve housing 1 is divided into upper and lower two positions, conveniently can realize dismounting, the operation of finely tuning pressure can be carried out again, structural stability, easy to operate.
When the air pressure of ventilating hole 6 reaches certain value time, movable stop valve 5 can be made to move upward, withstand spool 2 also to move upward, because the effect of valve core spring 3 can make limitation of movement, and two the position spacing changes up and down by regulating adjusting nut 4 to make safety valve housing 1, the pulling force of valve core spring 3 also will change, and can play fine setting effect.
Movable stop valve 5 is provided with cushion seal pad with ventilating hole 6 contact position, effectively prevent gas leak phenomenon; Spool top is provided with a draw ring, can directly pull out, and goes to realize exhaust voltage regulation result; Movable stop valve 5, spool 2 all adopt titanium alloy to make, and strengthen the stability of structure; The top of movable stop valve 5 is connected by plug tenon mode with spool 2, can facilitate installing/dismounting.
Above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment's technological scheme of the utility model.
